P0301 Ford - ranger 2002

Question

i just got all at once codes p0301,p0304,p0305 what could cause this

Answer 1

HI there,

When yo have this many codes on the same bank of the engine it usually indicates a possible timing issue. You may also have a leaking intake or faulty coil, but since it's on the same side I would start with a compression check to see if the timing is ok.
